# A 'Realistic Downstream Game' That Actually Computes River Flow

A browser-based downstream game that actually computes river flow using the lattice Boltzmann method, reproducing how a boat is pushed by currents flowing around rocks and by the eddies behind them. Created together with AI.

## Description

A realistic downstream game playable in the browser that actually computes river flow using the lattice Boltzmann method. The boat is pushed by currents that flow around rocks and by the eddies that form behind rocks, and the player navigates down the river while being affected by the flow. The author states that it was created jointly with AI.

川の流れを本当に計算した「リアルな川下りゲーム」をAIと一緒に作りました。
岩をよける流れや、岩の後ろのよどみに、船が押されたりします。（流れの計算には格子ボルツマン法を使っています）
